The electron is still round - short science news

Researchers have measured the shape of an electron’s charge with stunning precision, and found that it is perfectly spherical. This observation is in line with the so-called « Standard Model » of particle physics. However, the Standard Model is known be wrong, because it cannot explain why the universe exists. Several theories to replace the Standard Model have therefore been forwarded, that posit that there could be heavy particles in the electron’s presence. The current experiments, in which a beam of cold thorium-oxide molecules was fired into a chamber, and the emitted light from the molecules was measured, found no evidence for such heavy particles, as this would have distorted the emitted light pattern. Thus, the current alternative theories need rethinking, and the Standard Model, although not correct, is still the best we have to describe electrons and the universe’s mysteries.
